Chapter VI.

That without the grace of God we cannot make any diligent efforts.

And therefore though in many things, indeed in everything, it can be shown that men always have need of Gods help, and that human weakness cannot accomplish anything that has to do with salvation by itself alone, i.e., without the aid of God, yet in nothing is this more clearly shown than in the acquisition and preservation of chastity. For as the discussion on the difficulty of its perfection is put off for so long, let us meanwhile discourse briefly on the instruments of it. Who, I ask, could, however fervent he might be in spirit, relying on his own strength with no praise from men endure the squalor of the desert, and I will not say the daily lack but the supply of dry bread? Who without the Lords consolation, could put up with the continual thirst for water, or deprive his human eyes of that sweet and delicious morning sleep, and regularly compress his whole time of rest and repose into the limits of four hours? Who would be sufficient without Gods grace to give continual attendance to reading and constant earnestness in work, receiving no advantage of p. 425present gain? And all these matters, as we cannot desire them continuously without divine inspiration, so in no respect whatever can we perform them without His help. And that we may ensure that these things are not only proved to us by the teaching of experience, but also made still clearer by sure proof and arguments, does not some weakness intervene in the case of many things which we wish usefully to perform, and though the full keenness of our desire and the perfection of our will be not wanting, yet interfere with the wish we have conceived, so that there is no carrying out of our purpose, unless the power to perform it has been granted by the mercy of the Lord, so that, although there are countless swarms of people who are anxious to stick faithfully to the pursuit of virtue, you can scarcely find any who are able to carry it out and endure it, to say nothing of the fact that, even when no weakness at all hinders us, the opportunity for doing everything that we wish does not lie in our own power. For it is not in our power to secure the silence of solitude and severe fasts and undisturbed study even when we could use such opportunities, but by a chapter of accidents we are often very much against our will kept away from the salutary ordinances so that we have to pray to the Lord for opportunities of place or time in which to practise them. And it is clear that the ability for these is not sufficient for us unless there be also granted to us by the Lord an opportunity of doing what we are capable of (as the Apostle also says: “For we wanted to come to you once and again, but Satan hindered us” 1753
), so that sometimes we find for our advantage we are called away from these spiritual exercises in order that while without our own consent the regularity of our routine is broken and we yield something to weakness of the flesh, we may even against our will be brought to a salutary patience. Of which providential arrangement of God the blessed Apostle says something similar: “For which I besought the Lord thrice that it might depart from me. And He said to me: My grace is sufficient for thee: for my strength is made perfect in weakness:” and again: “For we know not what to pray for as we ought.” 1754
